Couldn't see if I had a restrictior by looking from the top. And yes I confirmed its a precision turbo, I know it's water cooled but not even sure now if it's a dual BB. Is there a way I can check this? The person who sold it to me told me it was but want to make sure.

 

Precision turbo went bad? No way!

Guess this is a common problem... Could this cause engine issues? I'll start looking at a rebuild then.

 

Under normal driving conditions and drag racing there is nothing wrong with the drain in that spot. I can't speak for high G turns at a road course on r-comps, but that doesn't concern most of us... I've had mine in that spot ever since I've had my car turbo'd and have had no problems with it (I autocross it too), as have many. There have even been people who drain the turbo to the drain plug on the pan (though I wouldn't recommend it) without issues. I sincerely doubt that is your problem.

My guess for your situation would be that you're not using the proper oil restrictor. The proper oil restrictor is crucial for turbos, especially for Precision turbos (or so I hear). The seals on your turbo may be bad already due to not using the proper restrictor.

You should definitely make sure you have the right restrictor, if that isn't it, then have your turbo seals checked out or replaced. I'd do that before I messed with the pan or turbo drain...

 

Great thanks for your post. With my setup is there a way of getting to the restrictior without removing the manifold?

Also could this cause any engine damage? Should I do a leaks own/compression test?

On the 8th, it still ran hard. 8.5 at 90mph so the engine seems ok but just to verify

 

Precisions may be different, but on my Garrett turbo we put the restrictor on the oil feed line where it connects to the turbo... so basically between the turbo and the oil feed line. I can't remember for sure, but I don't think I was able to reach it while it was on the car... I think the manifold/turbo had to be taken off the car.

I'm no expert, but I don't think the lack of the proper oil restrictor on the turbo could hurt the engine... just bad for the turbo as far as I know. I could be wrong though.

 

Got it. Is there a way of installing the restrictor on the oil feed instead of the turbo? I would hate to have to remove my turbo manifold to get to it.

Regarding the engine, I just wanted to make sure that if oil did get through the intercooler and into the eninge, if that could potentially damage it. I was going to take of the intercooler pipe by the intake manifold to see if there was any oil.

 

I'm with TerminatioN on this one. Many are using that location for oil return and not having problems including me. Especially with a watercooled BB turbo which needs very little oil.

 

Ok guys, have some updates here.

I raised the car, about 18 inches to get to the oil pan to try to adjust the hose a bit since it was kinked(Minor). I removed the turbo drail bolt and the oil pan started leaking. It filled up my tennis ball container and would have kept on leaking. Why would thiss happen if the car is raised? If its lowered, i would imagine it would leak even worse. Is this suppose to happen?

Also, can i put a restrictor in the oil relocation adaptor instead of the turbo?

Pictures added.

 

Please don't tell me you were crawling under that car with no jack stand....

I take it you've never seen a jack let loose. Do yourself (and your family a favor) pick up a set and work safely.






Now, when you say "turbo drain bolt" are you referring to the line on the pan? If oil was freely flowing out of your drain fitting on the pan, you either have too much oil in the car, or the fitting is too low. You want to the oil to have no resistance when flowing back into the pan/girdle, the backup in pressure will hose those precision seals almost instantly.


IK I have seen people with their returns here, but yours looks a tad lower than others
